Abstract: Embodiments disclosed herein relate to transition of a radio frequency module between a first operating state and a second operating state. The first and second states may be passive/slow (e.g., non-active) states or active/fast states. A passive state may include a sleep state, an idle state, an off state, or a low power state. An active state may include a receiving state or a transmitting state, for receiving and transmitting signals, respectively. If the first operating state is an active state and the second operating state is a passive state, the transition from the first operating state may be delayed such that the radio frequency module transitions directly from the first operating state to a third operating state. This enables the radio frequency module to avoid entering a passive second state with a slow settling time which can interfere with communications and operation of the radio frequency module.
